Dopamine is a powerful signal in the brain, influencing our moods, motivations, movements, and more. The neurotransmitter is crucial for reward-based learning, a function that may be disrupted in a number of psychiatric conditions, from mood disorders to addiction. Now, researchers led by Ann Graybiel, an investigator at MIT’s McGovern Institute, have found surprising patterns […]
Yiming Chen ’24, Wilhem Hector, Anushka Nair, and David Oluigbo have been selected as 2025 Rhodes Scholars and will begin fully funded postgraduate studies at Oxford University in the U.K. next fall. In addition to MIT’s two U.S. Rhodes winners, Ouigbo and Nair, two affiliates were awarded international Rhodes Scholarships: Chen for Rhodes’ China constituency and […]
This story also appears in the Winter 2025 issue of BrainScan. ___ McGovern investigator Nancy Kanwisher and her team have big questions about the nature of the human mind. Energized by Kanwisher’s enthusiasm for finding out how and why the brain works as it does, her team collaborates broadly and embraces various tools of neuroscience. […]
By analyzing brain scans taken as people watched movie clips, MIT researchers have created the most comprehensive map yet of the functions of the brain’s cerebral cortex. Using functional magnetic resonance imaging (fMRI) data, the research team identified 24 networks with different functions, which include processing language, social interactions, visual features, and other types of […]
From early development to old age, cell death is a part of life. Without enough of a critical type of cell death known as apoptosis, animals wind up with too many cells, which can set the stage for cancer or autoimmune disease. But careful control is essential, because when apoptosis eliminates the wrong cells, the […]
In a study of adults who use cannabis because they are seeking relief from pain, depression, anxiety, or insomnia, scientists at MIT and Harvard found no changes in brain activity after one year of self-directed use. The study, reported September 18, 2024, in JAMA Network Open, is among the first to investigate how the real-world […]
What is it like to give birth on Mars? Can bioengineer TikTok stars win at the video game “Super Smash Brothers” while also answering questions about science? How do sheep, mouse, and human brains compare? These questions and others were asked last month when more than 50,000 visitors from across Cambridge, Massachusetts, and Greater Boston […]
Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that initiates movement (“go”) and one that suppresses it (“no-go”). In a new study, MIT researchers have discovered an additional two pathways that arise […]
The National Academy of Medicine recently announced the election of more than 90 members during its annual meeting, including MIT faculty members Matthew Vander Heiden and Fan Wang, along with five MIT alumni. Election to the National Academy of Medicine (NAM) is considered one of the highest honors in the fields of health and medicine […]
